摘要： This invention discloses a process for synthesizing a hairy polymer particle which comprises the steps of (1) polymerizing a vinyl aromatic monomer by emulsion polymerization in an aqueous medium to produce core particles, (2) recovering the core particles from the aqueous medium, (3) dispersing the core particles in an organic solvent, (4) adding an organo-lithium compound to the dried core particles in the organic solvent to produce the hairless core initiator, and (5) utilizing the hairless core initiator to initiate the anionic polymerization of a conjugated diolefin monomer in an organic solvent to produce a solution of the hairy polymer particles. The hairy polymer nanoparticles can then be recovered from the organic solvent. These hairy polymer particles are comprised of (1) a core which is comprised of a polymer of a vinyl aromatic monomer and (2) hairs which are polymer chains of a conjugated diolefin monomer, wherein the hairs are covalently bonded to the core. The core is typically spherical in shape, has a diameter of less than 1000 nm, and is comprised of a crosslinked polymer of a vinyl aromatic monomer.

摘要： This invention relates to the reversible protection of hydroxy-silane functional groups by acid cleavable protecting groups. The development of reversible protecting groups greatly enhances the current utility of silanes while introducing further novel applications. For instance, reversibly protected silanes are of particular value in applications where room temperature cure and/or adhesion is of value, such as coatings, high resolution imaging, caulks, adhesives, sealants, gaskets, and silicones. Reversibly protected silanes can also be beneficially used in reticulating agents, and in sizing agents, tires, and release coatings. The incorporation of reversibly protected silanes into coating resins is of particular value. The reversibly protected silane can be incorporated into the coating resin by polymerizing a monomer containing the reversibly protected silane into the resin or by post-addition into the coating formulation. The reversibly protected silane remains protected under basic conditions, such as in a coating formulation that contains a volatile base, for instance ammonium hydroxide. However, deprotection occurs under mildly acidic conditions. Thus, as a coating formulation containing a volatile base dries the volatile base evaporates and deprotection occurs. This allows for controlled room temperature crosslinking to occur with hydroxy-functionalized polymers. The present invention more specifically discloses a silyl-acetal compound consisting of a silane having 3 or 4 acetal moieties bonded thereto.
摘要翻译：本发明涉及通过酸可裂解保护基团对羟基硅烷官能团的可逆保护。可逆保护基的发展大大提高了硅烷的当前用途，同时引入了进一步的新型应用。例如，可逆保护的硅烷在室温固化和/或粘合有价值的应用中是特别有价值的，例如涂料，高分辨率成像，填缝剂，粘合剂，密封剂，垫圈和硅酮。可逆保护的硅烷也可有利地用于网状剂，以及上浆剂，轮胎和脱模涂料中。将可逆保护的硅烷并入涂布树脂中是特别有价值的。可逆保护的硅烷可以通过将含有可逆保护的硅烷的单体聚合到树脂中或通过后添加到涂料配方中而被引入到涂料树脂中。可逆保护的硅烷在碱性条件下保持保护，例如在含有挥发性碱（例如氢氧化铵）的涂料配方中。然而，在弱酸性条件下发生脱保护。因此，当含有挥发性碱的涂料配方干燥时，挥发性碱蒸发并脱保护。这允许用羟基官能化的聚合物发生受控的室温交联。本发明更具体地公开了由与其键合的3或4个缩醛部分的硅烷组成的甲硅烷基缩醛化合物。
